Claims.

The invention relates to a device for guiding and deflecting glasscharges, and one of the objects of the invention is to provide means forguiding glass charges from a feeder to a forming ma- 5 chine, togetherwith means for deflecting the charges from the forming machine wheneverfor one reason or another the forming machine is stopped.

Another object of the invention is to provide a 1i device of thischaracter which is easily adaptable to molds of diiferent diameters orof different heights. A further object of the invention is to provide adeflector in which cooling water or air is automatically admitted whenthe deflector is moved to operative position. i

While the present invention is particularly intended for use withfeeders located a considerable distance above the forming machine, suchas illustrated in the patent to F. C. Flint, No. 1,764,832, granted June1'7, 1930, yet it is to be understood that the invention is equally welladapted to use with feeders located at aconventional distance above aforming machine. Also, of course, the

invention is not limited to use with any particular type of feeder, orwith any particular type of forming machine.

Variousother objects and advantagesof the invention will be apparent tothose skilled in the art, from the following detailed description, whentaken in connection with the accompanying drawings, in which,

Fig. 1 is a side elevational view of the device, in position to delivercharges to the molds.

Figure 2 is a similar view of the device, but. taken from the oppositeside.

Figure 3 is .a side elevational view similar to Figure 1, but showingthe deflector moved to position to deflect the charges from the molds.

Figure 4 is a transverse sectional view of the deflector, taken on line4-4 of Figure 3.

Figure 5 is a detail longitudinal sectional view of an auxiliary guide;and

Figure 6 is a transverse sectional view thereof, taken on line 6-6 ofFigure 5.

Referring to the drawings in more detail, numeral I indicates a pipewhich leads vertically downwardly from a glass feeder (not shown) to apoint over a rotatable mold table 2 carrying any desired number of molds3. The main purpose of this pipe, as described in the above-mentionedFlint patent, is to shield the mold charges from air currents whiledropping through considerable distances, and to protect the workmen.

Numeral 4 refers to a pipe section which, in the specific embodimentillustrated, is removably attached to the lower end of the pipe I, andthis pipe section carries the guide and deflector. Numeral 5 refers to aclamp member which is slotted horizontally as indicated by numeral 6,and which 5 is of course split vertically. The upper part of the clampmember is gripped to the lower end of pipe I by a lever I which has aportion arranged in the lugs 8; and the lower portion of the clampmember is gripped. to the pipe section 4 by a bolt 9 arranged in thelugs Ill. By operating the lever I the entire device, including theclamp member 5 is removed from or attached to the pipe I; or byoperating the bolt 9 the entire device is removed from or attached tothe clamp member.

The guide and deflector member, referred to generally by numeral II, ispivotally attached to the lower end of pipe section 4, as by hinges I2;and as shown in Figures 1 and 2 the joint between the lower end of pipesection 4 and the upper end of the guide and deflector is on a diagonalextending upwardly from the hinge, so that when the guide and deflectoris swung to the position shown in Figure 3 there will be ample provisionfor catching the glass charges in the deflector as they drop from thepipe section. It may be mentioned here that instead of mounting theguide and deflector on the pipe section 4, it may be desirable in someinstallations to mount it directly on the shield pipe I; or, where thefeeder is not a great distance above the molds, it may be attached toany supporting element below the feeder.

When the guide and deflector member II is in vertical position todeliver the glass charges to the molds, there is little contact with theglass charges, and cooling of the member is unnecessary, but when themember is moved to the position shown in Figure 3, to deflect thecharges, they slide down the deflecting member, and unless this memberwere cooled the glass charges would so increase its temperature thatthey would stick to it. I have therefore provided a water or air jacketI3 on the bottom and side portions of the guide member I I. Nipples I4and I5 are provided adjacent the upper and lower ends of the jacket. Tothe upper nipple I4 is attached a stop cock I6 provided with the usualoperating valve stem I1, and attached to the valve is a hose or flexiblepipe I8 leading from any desired source of water or air. The preferredmeans for opening and closing the valve will be described hereinafter.If water is used a hose or the like (not shown) may be attached to thelower nipple I5, to carry off the waste water to a drain.

Numeral l9 refers to an auxiliary guide which, if desired, may bemounted on the lower end of the guide and deflector member H. One of thepurposes of this auxiliary guide is to accurately center the moldcharges in the molds. That is, various auxiliary guides may be provided,having passages 20 of different diameters, to suit the diameters ofmolds of various sizes. Thus if the interior diameter of the molds to beused is three inches, an auxiliary guide having a passage ofapproximately that diameter may be mounted on the guide member ll,thereby assuring an exact centering of the mold charges in the molds.

The glass charges will contact to some extent with the wall of passage20, and this passage is therefore preferably cooled at all times. Forthis Purpose the auxiliary guide is provided with a water or air coolingjacket 2!. Nipples 22 and 23 are provided adjacent the top and bottom ofthe jacket, and hoses (not shown) are attached thereto to supply thecooling fluid to the lower nipple and carry it off from the uppernipple. The jacket is preferably provided with a vertical partition 24,to cause the cooling fluid to circulate around the jacket.

It is desirable that the auxiliary guide be vertically adjustable, sothat it may be properly positioned with respect to molds of differentheights. Of course any desired means may be employed for mounting theauxiliary guide for vertical adjustment on the guide and deflectormember II. In the particular embodiment illustrated the auxiliary guideis provided with an upwardly extending hollow stem 25 which is receivedin the lower end of the guide member, and is gripped in any desiredvertical position by operating a lever 26. This lever has a shankportion arranged in lugs 21 on the guide member. A shoulder on the shankportion engages one of the lugs, and the other lug is screw threadedlyengaged by the shank portion. Thus by operating the'lever the auxiliaryguide is clamped in position. Of course the lower portion of the guidemember II is split to permit this clamping operation.

In normal operation the parts are as shown in Figures 1 and 2, so thatthe charges delivered by a feeder will drop vertically downward into themolds as they are brought successively into charge receiving position.When the forming machine is to be stopped temporarily and the feedercontinued in operation to prevent variation in the temperature andcondition of the glass, the guide and deflector member II is moved tothe position shown in Figure 3, to defleet the charges from the molds toany suitable receiving receptacle. The preferred means for moving theguide between feeding position and deflecting position, and locking itin both positions, will now be described.

Numeral 28 refers to an operating lever keyed to a shaft 29 mountedinlugs 30. Also keyed to the shaft is a lever 3| which is pivotallyconnected to the upper end of an arcuate link 32; the lower end of thelink being pivotally connected to lugs 33 carried by the guide member.With these parts in the positions shown in Figure 1, the guide member islocked in its vertical position by reason of the lever 3| being past thedead center. To move the guide member to its deflecting position, it isonly necessary to throw the operating lever 28 to the right (Fig. 1)whereby the linkage will move the guide and deflecting members to theposition shown in Figure 3, so that the glass charges will now bedeflected from the forming machine to any desired receptacle. The guidemember is locked in this deflecting position by reason of the lever 3|being past dead center, as shown in Figure 3.

When the guide member was in its vertical feeding position it wasunnecessary to deliver cooling fluid to the jacket l3, but when it ismoved to deflecting position the guide mould quickly becomes overheated,causing the glass to adhere to it, if it were not cooled. It isdesirable that cooling fluid be admitted to the jacket l3 just as soonas the guide moves to deflecting position, and it is also desirable thatthe cooling fluid be automatically admitted, for otherwise it mightoccasionally be overlooked.

To automatically turn the valve to open position when the guide memberis moved to deflecting position, and to automatically close it when theguide member is moved to vertical feeding position, a link 34 ispivotally mounted at one end on the pipe section 4, and its opposite endis pivotally attached to one end of a link 35; the opposite end of thislink 35 having a square opening to receive the valve stem II which issquare in cross-section. Thus when the parts are in the positions shownin Fig. 1, the valve is closed, and when the guide is swung todeflecting position the links 34 and 35 cause the valve stem to beturned to open position. Of course the valve is again closed when theguide member is returned to its feeding position.

From the foregoing description it will be apparrent that this simplestructure provides means for guiding glass charges from a feeder to aforming machine, and accurately centering the charges in the molds,means for automatically cooling the guide when it is moved to deflectingposition, thereby saving in the use of the cooling medium and at thesame time assuring proper cooling, means for locking the guide anddeflector member in its feeding position and its deflecting position,means for varying the size of the outlet passage by mounting differentauxiliary guides on the lower end of the guide and deflector member, andrendering the device adaptable to molds of different heights by thevertical adjustment of the auxiliary guide.
